The answer is D
Explanation:5x^5-44x^3-9x=0
X(5x^2+1)(x-3)(x+3)=0
X(x+3)(x-3)=0
X=0,x=-3,x=3

Answer:
Option B: 1/4(n - 64)
Step-by-step explanation:
As given that:
= 1/4n - 16
By taking 1/4 common: 4 will get multiplied by 16
As 16*4 = 64 so,
The expression would become:
=1/4(n -64)

Answer:
Step-by-step explanation:
x-4=0
x=4
i solve by synthetic division.
4| 1 -7 14 -8
| 4 -12 8
___________
| 1 -3 2 | 0
![x^3-7x^2+14x-8=(x-4)(x2-3x+2)\\=(x-4)[x^2-x-2x+2]\\=(x-4)[x(x-1)-2(x-1)]\\=(x-4)(x-1)(x-2)](https://tex.z-dn.net/?f=x%5E3-7x%5E2%2B14x-8%3D%28x-4%29%28x2-3x%2B2%29%5C%5C%3D%28x-4%29%5Bx%5E2-x-2x%2B2%5D%5C%5C%3D%28x-4%29%5Bx%28x-1%29-2%28x-1%29%5D%5C%5C%3D%28x-4%29%28x-1%29%28x-2%29)
x-intercepts are (4,0),(1,0),(2,0)
put x=0
y=-8
y -intercept is (0,-8)
